Northrop Grumman Corp recently rolled out its new B-21 "Raider" jet, the first of a new fleet of long-range stealth nuclear bombers for the United States Air Force.
About:
The B-21 Raider will employ cutting-edge stealth technologies to carry out nuclear missions and long-range bombing.
Each aircraft costing about $2 billion or Rs 1624 Crore to be built.
The B-21 Raider will be a subsonic aircraft.
Speed: Average of 563 miles per hour.
The B-21 Raider, which takes its name from the 1942 Doolittle Raid over Tokyo, will be slightly smaller than the B-2 to increase its range.
Other changes likely include advanced materials used in coatings to make the bomber harder to detect, new ways to control electronic emissions.
So the bomber could spoof adversary radars and disguise itself as another object, and use of new propulsion technologies.
Modernisation:
The bomber is part of the Pentagon's efforts to modernise all three legs of its nuclear triad, which includes silo-launched nuclear ballistic missiles and submarine-launched warheads, as it shifts from the counterterrorism campaigns of recent decades to meet China's rapid military modernisation.
The U.S Air Force plans to build 100 that can deploy either nuclear weapons or conventional bombs and can be used with or without a human crew.
